However, conventional manufacturing methods frequently grapple with limitations, such as challenges in shaping intricate geometries, extended processing durations, elevated porosity, and substantial shrinkage deformations. Direct additive manufacturing (dAM) technology stands out as a state-of-the-art solution for ceramic oxides production. It facilitates the one-step fabrication of high-performance, intricately designed components characterized by dense structures. Importantly, dAM eliminates the necessity for post-heat treatments, streamlining the manufacturing process and enhancing overall efficiency. This study undertakes a comprehensive review of recent developments in dAM for ceramic oxides, with a specific emphasis on the laser powder bed fusion and laser directed energy deposition techniques. A thorough investigation is conducted into the shaping quality, microstructure, and properties of diverse ceramic oxides produced through dAM. Critical examination is given to key aspects including feedstock preparation, laser–material coupling, formation and control of defects, in-situ monitoring and simulation. This paper concludes by outlining future trends and potential breakthrough directions, taking into account current gaps in this rapidly evolving field.","PeriodicalId":502508,"journal":{"name":"International Journal of Extreme Manufacturing","volume":"1 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141266216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among a variety of patterning techniques, transfer printing emerges as one of the most efficient, cost-effective, and scalable methods. It boasts the ability for high-throughput fabrication of 0-3D micro- and nano-structures on flexible substrates, working in tandem with traditional lithography methods. This review highlights the critical issue of transfer printing: the flawless transfer of devices during the pick-up and printing process. We encapsulate recent advancements in numerous transfer printing techniques, with a particular emphasis on strategies to control adhesion forces at the substrate/device/stamp interfaces. These strategies are employed to meet the requirements of competing fractures for successful pick-up and print processes. The mechanism, advantages, disadvantages, and typical applications of each transfer printing technique will be thoroughly discussed. The conclusion section provides design guidelines and probes potential directions for future advancements.","PeriodicalId":502508,"journal":{"name":"International Journal of Extreme Manufacturing","volume":"22 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, molecular dynamics (MD) simulations of double-grits interacted grinding of GaN crystals were performed, and the grinding force, coefficient of friction, stress distribution, plastic damage behaviors, and abrasive damage were systematically investigated. The results demonstrated that interacted distance with both radial and transverse directions achieved better grinding quality than that with only one direction or single-grit grinding. The grinding force, grinding induced stress, subsurface damage depth, and abrasive wear increases as the transverse interacted distance increases. However, the influence laws of the interacted distance on atom number of phase transition and dislocation length are not distinct. Appropriate interacted distances between abrasives can decrease grinding force, coefficient of friction, grinding induced stress, subsurface damage depth, and abrasive wear during the grinding process. Grinding test combined with the cross-sectional TEM detection verified the reliability of the simulated damage behaviors, i.e. amorphous, high-pressure phase transition, dislocations, stacking faults, and lattice distortions. The results not only enhance the understanding of damage accumulation and material removal caused by the coupling actions of abrasives in grinding process, but also provide a feasible approach for the wheel design of ordered abrasives.","PeriodicalId":502508,"journal":{"name":"International Journal of Extreme Manufacturing","volume":"90 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139612932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a promising idea to shape inorganic materials in three-dimensional (3D) forms to reduce their weight while maintaining high mechanical properties. A popular strategy for the preparation of 3D inorganic materials is to mold the organic-inorganic hybrid photoresists into 3D micro- and nano-structures and remove the organic components by subsequent sintering. However, due to the discrete arrangement of inorganic components in the organic-inorganic hybrid photoresists, it remains a huge challenge to attain isotropic shrinkage during sintering. Herein, we demonstrate the isotropic sintering shrinkage by forming the consecutive -Si-O-Si-O-Zr-O- inorganic backbone in photoresists and fabricate 3D glass-ceramic nanolattices with enhanced mechanical properties. The femtosecond (fs) laser is used for two-photon polymerization (TPP) to fabricate 3D green body structures. After subsequent sintering at 1000 ℃, high-quality 3D glass-ceramic microstructures can be obtained with perfectly intact and smooth morphology. In-suit compression experiments and finite-element simulations reveal that octahedral-truss (Oct-Truss) lattices possess remarkable adeptness in bearing stress concentration and maintain the structural integrity to resist rod bending, indicating that this structure is a candidate for preparing lightweight and high stiffness glass-ceramic nanolattices. 3D printing of such glasses and ceramics has significant implications in a number of industrial applications, including metamaterials, microelectromechanical systems, photonic crystals, and damage-tolerant lightweight materials.","PeriodicalId":502508,"journal":{"name":"International Journal of Extreme Manufacturing","volume":"58 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139164334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
